Is the GMC Jimmy automatic or 4 wheel drive?
I have an automatic 2000 GMC Jimmy. It has automatic 4-Wheel Drive. After a recent snow storm, in which I was stuck, I could not get it into 4-wheel drive by selecting the automatic button, the 4-hi button, or the 4-low button. The buttons would just flash and the 4-wheel would not engage.
Why does my GMC 4×4 won’t engage?
Not using 4wd is ne of the biggest causes of failure ! Take it to a mechanic. Everything’s a guess from here on out. @dagosa The new style transfer case’s like what in my 06 GMC, are not like the old style that you need to use once in a while. The new ones (been this way since the late 90’s) are shifted with motor on side of transfer case.

Why does my 4 wheel drive not engage?
The transfer case could pose another reason why your 4 wheel drive fails to engage. This could be due to the vehicle not coming to a complete stop to allow it to engage. This is because the splined pin and gears of the actuator need to align 100% with the gears inside the transfer case.
Is there a problem with my GMC Jimmy 4WD?
If you have 4 button Autotrac the transfer cases sometimes have clutch problems and use special blue syn fluid to smooth out. The Bang comes going back to 2WD. When going into 4WD, you hear the clicking of the relays and feel it shift and hear a low whine/rumble. 4LO seems to be working as advertised.

Why does my GMC Jimmy make Rev 2 / 4 noise?
That rev/2/4 thing is caused by an internal broken Sunshell and the neck breaks off all at once usually from drivetrain shock as hard 4wd or towing. Noise could be many things as u-joints, hubs, brakes, tires etc so need to look under it and start checking. Also look at the transfer case fluid and change every 50k as well as trans fluid/filter.
How does transfer case work on GMC Jimmy 4WD?
For 4Lo the transfer case has an encoder motor that is on the transfer case that engages a lower gear when you stop, put trans in neutral and push 4 lo and a clunk is heard. Again a sensor on the transfer case to tell TCCM it is engaged. Hope that wasn’t too confusing.
